Hi Im Tricia an organic gardener I grow organically for a healthy and safe food supply, for a clean and sustainable environment, for an enjoyable and rewarding experience. Aquaponics is a great growing technique I'm here with Ross Tessien. Hi Ross, Hi there nice to meet you, he's with wood fire power and we're here in his aquaponics greenhouse were going to explain how it all works.
Aquaponics is a combination of hydroponics and aquaculture and it can be done at any scale and this way you have food and fish all year long. In aquaponics you have edible fish such as to tilapia, koi, perch, bass and trout and those fish produce waste, bacteria converts their waste to fertilizer for plants, plants use that bacteria by product to grow, so the waste laden water is pumped out of the tank into the growing systems where the plants and bacteria clean the water and then it's pumped back into the fish tank. This way you get tasty fish to eat and you grow some great plants. There are as many ways to set up an aquaponic system as there are growers.
Today we're going to be talking about a couple of the components for aquaponic growing.
The first system is a fish raceway this can be as large as something like this five hundred and fifty gallon water tank and as small as a twenty gallon aquarium. Choose your fish based on the climate that you live in and on the environment that you can provide for them. Your fish tank should be at the highest point of your system this way the fish waste solids will flow out with gravity.
The first system we're gonna talk about are deep water culture tables like these. This system consists of these long troughs with rafts floating that support the plants. Deep water culture is best suited to plants that produce edible leaves such as lettuce, basil, cilantro and mustard. The plants are put in these little net pots and the net pots rest in the holes in the buoyant rafts and the roots go down into the water below. The great thing about growing aquaponically is that you can harvest your lettuce and you can keep it on the kitchen counter for a few weeks as long as you change the water every day and just pull off the leaves as you wanna make a salad.
The next type of system were talking about is a flood drain table and this is good for larger vegetables like kale or root crops. These tables have a media like perlite or gravel that the plants grow in and the water flows in and then drains out. What do we have their "woohoo" look at that beet beautiful.
This next system we're gonna show you is for starting your seeds and growing micro greens. After planting seeds in the trays the trays are placed in the table of trickling water insulated if necessary to keep them warm until germination. After germination the trays are placed below where there are heat or light lamps.
The last system we're looking at today is these dutch buckets. Dutch buckets are good for bigger fruit and vegetables like tomatoes, peppers and melons. The bucket snap into this pipe and they have lines in the top the water comes in from the top and then drains down the pipe. The last system is the sump this is the lowest part of the system and it's where the water collects before being pumped back up into the fish tank. In some systems like this one you don't need a sump your deep water tables are your sump.
That was just a quick survey on different types of Aquaponic systems I suggest you go to groworganic.com and purchase the plans to build your own as well as an instructional DVD. So raise your own fish grow your own plants farm aquaponically and grow organic for life!
